SPECIFICATION forming part Of Letters Patent No. 660,032, dated. October 16, 1900. Application filed April 28, 1900- Serial No. 14,734. (No model.)

To roll whom/ it may concern.-

Be it known that I, JOHN W. SEAVER, a citizen of the United States, and a resident of Cleveland, Ohio, have invented certain Improvements in Coke-Loading Machines, of which the following is a specification.

My invention relates to that class of apparatus intended to receive coke from a cokingoven and load the same into open-top cars, the main object of my invention being to so construct such apparatus as to prevent waste of coke by spilling same outside of the car, and a further object being to construct a durable form of apparatus of large capacity and providing for the expeditious handling of the coke with a minimum of labor.

In the accompanying drawings, Figure 1 is a front view of a coke-loading apparatus constructed in accordance with my invention. Fig. 2 is a side elevation of the same with one of the end towers removed and showing the upper and lower girders in section. Fig. 3 is a sectional plan view of the bottom girder or carriage of the apparatus with the mechanism for traversing the same. Fig. 4 is a side elevation of the main hoisting-drum and of the gearing for operating the same. Fig. 5 is a transverse section of the loading-pan. Fig. 6 is a longitudinal section of part of the same. Fig. 7 is a detached view of part of the mechanism employed, and Figs. 8 and 9 are diagrams illustrating modifications of the invention.

The apparatus has a base-frame or girder 1, provided at each of its four corners with wheels 2, which are adapted to run upon rails 3, laid in front of the row of coking-ovens, part of the foundation of such row of ovens being shown at at in Fig. :2 and part of the hearthplate of one of the ovens being shown at 5 in said figure.

From each end of the base-frame or girder of the apparatus rises a skeleton tower 6, these towers being connected together at the top by a longitudinal girder 7, so as to form a strong and well-braced structure. The loading-pan 8 is suspended between the towers 6 by means of hoisting ropes or chains, the hoisting-tackle being of any desired character appropriate for the work to be performed. A set of hoisting-tackle is provided at each end of the loadingpan, and in the present instance the end of one of the hoisting-chains 9 is connected to one of the end frames of the pan at 10, the chain passing around a sheave 11 on a shaft which is adapted to hearings on the top girder 7, thence down to and around a sheave 12 on the end frame of the pan, thence up to and around another sheave l3 alongside of the sheave 11, and thence down to the winding-drum 14, which is carried by a shaft adapted to hearings at the base of one of the towers 6. The opposite end of the pan has similar hoisting-gear, the final run of the hoisting-chain 9, however, passing around a sheave 15, mounted in bearings on the base frame, and thence running longitudinally to the winding-drum 14.

Power is applied to the winding-drum 14- from an electric or other suitable motor 16, mounted on one of the end towers, this power being transmitted through suitable intervening shafts and spur-gears, as shown, for instance, in Fig. 4.

The traversing of the entire structure longitudinally on the rails 3 is effected by means of an electric or other suitable motor 17, mounted on the base-frame and driving the axle of one of the pairs of supporting-wheels of the apparatus through the medium of an interposed shaft and spur-gears, as shown in Fig. 3. Hence provision is afforded for moving the apparatus to any point on the longitudinal track 3 and for raising and lowering the loading-pan between the end towers 6.

The loading-pan has longitudinal girders 18 and 19, Fig. 5, and mounted upon and securely confined to these girders are transverse I-beams 20, to which the floor of the pan is secured, said floor consisting, by preference, of a series of rectangular plates 21, extending from one beam 20 to the other and suitably confined to said beams, these plates being ribbed upon the back in order to give them the desired strength and the upper faces of the plates being flush with each other, so that the bottom of the pan presents a smooth surface. The end frames 22 of the pan are composed of suitable sheet-metal plates and angle bars or shapes bent to the desired form and having said sheet-metal plates secured thereto, and the pan has at its lower end a movable gate or grating, preferably made in twoor more sections, that shown in the drawings being composed of two sections. Each section of the gate consists of a shaft 23, of square or other polygonal crosssection, mounted so as to be free to turn in a bearing in the end frame of the pan and in a central standard or bracket 24, and upon this shaft are strung or threaded a series of blocks 25, with projecting webs 26, to which are bolted or riveted the bars 27, forming the fin: gers of the gate.

Upon the inner side of each of the end towers of the apparatus are a pair of parallel grooved guides 30 and 31, adapted for the reception of antifriction-rollers 32, carried by suitable brackets on the adjacent end frame of the loading-pan, the lower portion of each of these guides being Vertical, but its upper end being curved or bent forwardly, as shown in Fig. 2, whereby when the loading-pan is raised from its lowermost position the first portion of the raising operation will be in a vertical direction, but the latter portion will be in an upward and forward direction, a reverse movement accompanying the lowering of the pan. As will be seen on reference to Fig. 2, the guides and the hoistiugtackle maintain the loading-pan in an inclined position at all elevations, so that upon the opening of the gate or grating at the lower end of the pan the coke or other material in the pan will be discharged by gravity therefrom. The coke is pushed from the oven over the hearth-plate 5 and into the loading'pan when the latter is in its lowermost position,'and the loaded pan is then raised vertically until its forward end approaches the level of the top of a car (3 standing upon a track in front of the loading apparatus, further rising movement of the pan being then attended by a forward or projecting movement, so that by the time the loading-pan reaches its highest position the discharge end of the pan will project considerably beyond the side of the car. Hence when the load of coke is discharged from the pan into the car there will be no possibility of any of the particles of coke dropping outside of the latter, thus overcoming a serious objection to that form of loading apparatus in which the toading-pan has simply a vertical movement and in which, consequently, a certain amount of space must be left between the side of the car andv the delivery end of the pan, which space exists when the pan has been raised and which causes a waste of coke because of the dropping of pieces of the latter between the delivery end of the pan and the side of the car.

In order to provide for the opening and closing of the gate at the lower end of the loading-pan, the shaft 23 of each section of the gate has outside of the corresponding end frame of the pan an arm 33,which is connected, by means of a link 34, to one arm of a lever 35, hung to a bracket on said end frame, the other arm of said leverhaving an antifrictionroller 36, which is adapted to engage with a grooved guide 37 on theinner side of the adjacent end tower of the apparatus, said grooved guide 37 being substantially of the same conformation as the grooved guides 30 and 31, which receive the antifriction-rollers 32 of the loading-pan. In the present instance, however, the upper end 38 of each of the guides 37 is pivoted at 39 and is grooved on its outer face for the reception of an antifriction-roller 40 on one arm of a bell-crank lever 41, which is hung to a suitable bracket on the tower 6, the other arm of said bell-crank lever being connected by a link 42 to an arm 43 on a shaft 44, free to turn in hearings on the top girder 7 of the apparatus, one of the shafts being tubular and the other passing through it, as shown in Fig. 7. Each of these shafts extends into a cabin 45 on one of the end towers 6and is provided with an arm or lever 51, whereby it can be readily operated, said cabin also containing the switches and regulators for the hoisting and traversing motors of the apparatus and being provided wit-h trolleyarms 46 and 47 for conveying the current to and from the wires 48, which are suitably su pported above the apparatus. When the lifting-pan has reached the limit of its upward movement, the antifriction-roller 36 occupies a position in the pivoted upper portion 38 of the guide 37. Hence by swinging said pivoted portion of the guide inward the lever 35 will be'vibrated, and that section of the retaining-gate controlled by said lever will be swung outward, so as to discharge the contents of the loading-pan, which are normally retained thereby, provision being thus afforded for discharging only a portion of the contentsof the pan at one time by operating one section of the gate or for discharging the entire contents of the pan by a simultaneous operation of both sections of the gate. By swinging the upper sections 38 of the guides 37 back into their normal position the gatesections will be again swung downwardly, so as to close the lower end of the pan.

Automatic operation of the gate may, as will be evident, be effected by so forming the upper ends of the guides 37 that they will normally occupy a position approximating that'shown by dotted lines in Fig. 2,whereby the gate will be gradually swung open as the pan approaches the limit of its upward move- .ment and will be gradually closed as the pan descends. While I prefer also to so arrange the guides that the loading-pan will, as it is lifted, have first a vertical and then a combined vertical and forward motion, this is not essential to every embodiment of my invention. Forinstance,the guide may be arranged, as shown at 49 in Fig. 7, so that the loadingpan will move forwardly throughout the entire lift, or instead of using guides for engaging with and controlling projections on the loading-pan the movement of the latter may be guided in other ways-as, for instance,

by hanging the pan upon levers 50, (see Fig.

8,) so mounted as to impart to the pan the desired upward and forward and inward and downward movement.

Although the apparatus which I have described is intended for loading coke, it may, as will be evident, be used for loading cars with coal, grain, ore, or other material.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The combination in apparatus for loading cars, of a suitable framework, a loadingpan, normally inclined so as to discharge its load, hoisting mechanism for said pan and controlling devices whereby the pan, as it is lifted is projected bodily forward so as to carry its delivery end over the top of the car, substantially as specified.

2. The combination in apparatus for loading cars, of a suitable framework, a loading pan, normally inclined so as to discharge its load, hoisting mechanism for said pan, and controlling devices for the pan, whereby during the first portion of its rising movement the pan travels vertically and during the latter portion of said rising movement is pro jected bodily forward, substantially as specified.

In apparatus for loading cars, the combination of a suitable framework, a loadingpan normally inclined so as to discharge its lead, hoisting mechanism for said pan and guides for the pan carried by said framework, the lower portions of said guides being substantially vertical and the upper portions forward ly bent or inclined,substant-ially as specificd.

The combination in apparatus for loading cars, of a suitable framework, a loadingpan normally inclined so as to discharge its load, hoisting mechanism for raising said pan without tilting the same, a gate closing the lower end of said loading-pan, and manuallyoperated devices for controlling said gate,sub stantially as specified.

5. The combination in apparatus for loading cars, of a suitable framework, a loadingpan, hoisting m eohanism therefor, a gate closing the lower end of the pan, a guide on the framework having a movable portion whereby said guide controls the position of the gate, and means for shifting the movable portion of the guide, substantially as specified.

6. The combination in apparatus for loading cars, of a suitable framework, a loadingpan, hoisting mechanism therefor, a gate at the lower end of the pan, a guide on the framework, said guide having a swinging section, means whereby said guide is caused to control the position of the gate, a shaft on the fixed structure, and connections between said shaft and the swinging section of the guide, substantially as specified.

7. The combination in a loading-pan, of the longitudinal and transverse beams or girders, and end frames, with a sectional bottom composed of plates supported by said transverse girders, substantially as specified.

8. The combination of the loading-pan with a retaining-gate consisting of a longitudinal shaft having blocks strung or threaded thereon, said blocks carrying the bars of the gate, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
